I use the iRex since the kindle was not available to overseas customers. I like the fact that you can write on it. It takes all formats. I find PhotoReading on it okay. It is slower than I flipped pages of books. But then books are slower than I PhotoRead under computer. So I always PhotoRead, everything before I transfer it to be iRex.I do like it because it is significantly faster activating than on a computer. It is much easier on the eyes.
